Overview
- The new tariff action is effective immediately at a 0% rate for Chinese semiconductors.
- The rate is scheduled to rise on June 23, 2027, with the specific level to be announced at least 30 days in advance.
- The measure is explicitly additional to existing 50% duties on Chinese chips, which remain in force.
- The decision will be formalized in the Federal Register on December 29, 2025.
- USTR says the move follows a year-long probe focused on legacy chip exports and concludes China’s policies unreasonably restrict U.S. commerce.
